Hit the beach
It just so happens that in San Juan, there are several great beaches - but two of the most notable ones are Ocean Park and Isla Verde. For a mix of locals and tourists alike, check out Ocean Park Beach - one of the most popular beaches in San Juan that boasts mild waves for surfing, a small shoreline, and little to no crowds on week days. Another must see beach in San Juan is Isla Verde, where most of the large hotels are located. The vibe in Isla Verde is decidedly more touristy, but the white sand and warm water make it worth a visit.
